United States: Microsemi Introduces Mega-Contrast Dimming Technology for Enhanced Black Levels and Dynamic Contrast in LCD TVs.Byline: prashant03 Microsemi Corporation (Nasdaq:MSCC MSCC Motlow State Community College (Lynchburg, TN) MSCC Morgan Sports Car Club MSCC Manila Sports Car Club MSCC Mission Springs Community Church (Fremont, CA) MSCC Mazda Sports Car Club ), a leading manufacturer of high performance analog/mixed signal integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. and high reliability semiconductors, announced today the first in a new family of cold cathode A cathode in a gas-filled electron tube that is not heated by a filament in order to excite the electrons and cause current flow. The voltage potential within the tube is sufficient to ionize the gas in the tube and cause current flow. fluorescent lamp fluorescent lamp Type of electric discharge lamp consisting of a glass tube filled with a mixture of argon and mercury vapor. A current of electricity causes the vapor to produce ultraviolet radiation that, in turn, excites a phosphor coating on the inside of the tube, (CCFL (Cold Cathode Fluorescent Lamp) Same as CCFT. ) backlight back·light n. A type of spotlight, used in photography, that illuminates a subject from behind. tr.v. back·light·ed or back·lit , back·light·ing, back·lights inverter (1) A logic gate that converts the input to the opposite state for output. If the input is true, the output is false, and vice versa. An inverter performs the Boolean logic NOT operation. (2) A circuit that converts DC current into AC current. Contrast with rectifier. controller products that feature advanced mega-contrast dimming technology that significantly improves display quality and performance for 26- to 37-inch LCD TVs. Microsemi's new LX6523A(TM) CCFL inverter controller is the first to embed its patented PureBLACK(TM) mega-contrast dimming technology, developed by Dr. Xiaoping Jin, inventor of Microsemi's widely adopted Jin Balancer that dynamically adjusts lamp voltages to match multi-lamp currents to tight tolerances. PureBLACK technology delivers superior black levels and dynamic contrast performance by building upon the Jin Balancer's ability to ensure lamp striking with very small duty cycles. Microsemi plans to include its advanced mega-dimming capability in future controllers for 40-inch-and-larger displays that use the latest High Voltage LCD Integrated Power Supply (HV-LIPS) topology. "We've taken another important step in CCFL backlight innovation with PureBLACK technology," said Tom Kapucija, director of marketing at Microsemi's Analog Mixed Signal Group. "It will enable high-end image quality across all display sizes and price points, demonstrating Microsemi's continuing commitment to extending performance/price capabilities while improving the consumer's visual experience," he said. Microsemi's expanding family of backlighting back·light n. A type of spotlight, used in photography, that illuminates a subject from behind. tr.v. back·light·ed or back·lit , back·light·ing, back·lights , sensor and color-management system solutions drive both conventional and emerging high-efficiency LED backlight solutions in a wide variety of TV, notebook computer, automotive and other display platforms and applications. The LX6523A controller features soft-start capability, fault indication, and flexible configuration support for push-pull, full-bridge or half-bridge drive topologies for ultra-low-cost displays solutions. It provides all key functions needed for LCD TV / monitor displays in a simplified controller that also provides reliable lamp striking, comprehensive brightness control modes, and support for 24V inverter topologies in existing backlight applications. The LX6523A controller also features tighter lamp current accuracy as compared to competitive solutions. Copyright : Euclid Infotech Pvt. Ltd. Provided by Syndigate.info an Albawaba.com company |
